MP1584EN 3A DC-DC Fixed 5V Step-Down Buck Converter Module

The MP1584EN 3A DC-DC Fixed 5V Step-Down Buck Converter Module is an ultra-compact, high-frequency voltage regulator engineered to deliver a rock-solid 5V output for your sensitive electronics. Utilizing the highly efficient MP1584EN IC, this non-isolated step-down module seamlessly converts a wide DC input voltage range of 6V to 28V down to a stable, fixed 5V output. By replacing the standard mechanical potentiometer with a precision fixed-resistance feedback circuit, this module completely eliminates voltage drift caused by mechanical vibrations. Capable of delivering up to 3A of peak current and operating with an impressive conversion efficiency of up to 96%, it solves the critical problem of powering high-current 5V devices safely in space-constrained and weight-sensitive builds.

Thanks to its miniature 22x17mm footprint and vibration-resistant fixed output, this buck converter is perfectly suited for dynamic and mobile applications, including RC drones, smart car chassis, and custom robotics. It serves as an excellent UBEC (Universal Battery Elimination Circuit) for stepping down high-voltage LiPo battery packs to cleanly power 5V flight controllers, receiver setups, or FPV camera systems. Furthermore, its high 1.5MHz switching frequency guarantees incredibly low output ripple, making it the ideal clean power source for sensitive microcontrollers and IoT development boards, including Arduino, Raspberry Pi, ESP32, and ESP8266. Whether you are designing an automated sensor array or upgrading a 3D printer, this module provides reliable and efficient power management.

Features:

• Fixed 5V Output: Utilizes a precision fixed-resistor circuit to eliminate voltage drift, ensuring your 5V logic hardware remains safe from accidental overvoltage.
• Wide Operating Input: Readily accepts a versatile DC input voltage range from 6V to 28V, accommodating automotive systems and multi-cell LiPo batteries.
• High Current Capacity: Safely delivers up to 3A of peak current and 1.5A of continuous current without the need for an external heat sink.
• Exceptional Efficiency: The 1.5MHz high-frequency switching architecture provides up to 96% power conversion efficiency, vastly reducing heat dissipation.
